Abstract

The method involves driving a turbine of the respective exhaust gas turbocharger with air under pressure (cold test) and testing at least using measurement parameters on the compressor of the respective turbocharger. The air pressure is at least partly generated by an internal combustion engine driven at low speed. Compressed air at the exhaust gas side of an engine driven at low speed is used to drive the turbine of a turbocharger to be tested.
